Key features of the LA SPORTIVA TX4 Evo GTX

• GORE-TEX Extended Comfort membrane: Provides complete waterproofing and breathability (bluesign® certified), keeping feet dry even during prolonged use in wet conditions.
• Vibram Megagrip outsole: Combined with 4 mm-deep lugs and a Climbing Zone at the toe, it provides exceptional grip on rock and scree.
• Impact Brake System™ technology: The innovative lug arrangement absorbs impact on contact with the ground and improves braking on steep descents.
• Resole Platform™ system: Allows worn outsoles to be replaced quickly and easily by authorised repairers, extending the life of the boot.
• Ortholite® Hybrid Approach insole: The 4 mm-thick insole made from recycled materials provides lasting comfort and additional cushioning.

In practice

On technical approaches and via ferratas, the climbing zone at the front of the outsole enables precise foot placement on small rock ledges, while the asymmetrical lacing system (inspired by climbing shoes) ensures a close fit.

On steep scree descents, Impact Brake System technology and the cushioned EVA midsole reduce stress on the joints by effectively absorbing impacts and preventing slips.

In rainy weather and when crossing wet meadows, the GORE-TEX membrane reliably blocks water ingress while maintaining a high level of breathability, helping to prevent feet from overheating.
